Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electrically heated bedding that collects heat from the human body. Conventional technology The electrically heated bedding described above is, for example, disclosed in Utility Model Publication No. 62-4039.
As described in Japanese Patent Application No. 0, there is a thermotherapy device which is made of a planar heating element that emits heat and a cushion mat that is housed inside an outer cover to prevent sweating.

Problems to be Solved by the Invention Electrically heated bedding for healthy people had the following problems. FIGS. 6 and 7 are conventional examples of this, and when a person sleeps on this heat treatment device and sweats, the surface of the body and the skin cover 11 come into close contact because the skin cover 11 is flat. This results in a sticky and unpleasant feeling due to sweat, and even though the cushion has unevenness, it is not effective in dispersing sweat because the outer skin cover 11 on the surface is flat. Hygienic considerations such as treatment in case of adhesion have been insufficient, and the above improvements have been desired for electrically heated bedding intended for healthy people.

Means for Solving the Problems The present invention aims to solve the above-mentioned technical problems and provide a comfortable sleeping environment. A heating element provided at the bottom,
A bedding main body is constituted by the elastic body and a surface material covering the heating element, the elastic body and the surface material have breathability, and an adhesive material having surface material breathability in the groove formed on the surface material side of the elastic body. They were brought into close contact with each other with a groove interposed therebetween to form a groove on the surface.

Note that the adhesive was provided with ventilation means whose mesh was finer than the body width of the mite.

Function The present invention provides grooves on the surface of the electric heating bedding to prevent sweating during sleeping, thereby providing an effect of dissipating moisture by using the grooves as passages.

In addition, when improving heat absorption by making the surface material breathable, consideration should be given to making the bedding resistant to dust mites by applying special woven fabric or special processing to create ventilation holes that do not allow dust mites to pass through. You can prevent it from becoming a residence. EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a simplified external view of one embodiment of the present invention,
Figure 2 is a sectional view of section A. The structure of the present invention basically consists of a surface material 1, elastic bodies 3 and 5 housed in the surface material 1, and a heating element 4 located between the two elastic bodies to form a certain rectangular bedding. It constitutes the main body 10.

The heating element 4 is located between the two elastic bodies 3 and 5, and the elastic body 3 of the surface material tllll has a groove 7 on the surface material 1 side, and the surface material 1 is placed in close contact with the surface material 1 along the groove 7. Grooves 2 are formed on the outer surface by bonding the groove 7 portions of the surface material 1 and the elastic body 3 with a breathable adhesive 30. The surface material 1 may be plain weave cloth, etc.
A part of the side surface has a chuck for attaching and detaching the heating element 4 and the elastic body 5 such as a cushion. The elastic body 3 is made of open-cell urethane foam or vegetable fibers such as palm leaves treated with resin to provide air permeability. The heating element 4 is a sheet heating element similar to an electric blanket, a cord heater, etc., and is flexible. The elastic body 5 has cushioning properties as a closed foam urethane foam.

Next, the operation of the above configuration will be explained.

When the heating element 4 is energized and heated, the hot air flows toward the surface material 1 through the elastic body 3, and since the adhesive material 30 has air permeability, it is emitted to the outside through the gaps between the textures of the surface material 1. In this case, the electric heating bedding main body 10 is used by a user (human body) sleeping on the upper part, as shown in FIG. 3, and a blanket, comforter, etc. is hung on the upper part.

Therefore, the hot air generated by the electric heating bed main body 10 and released to the outside directly warms the user, and at the same time
The bedding itself consists of a human body or a blanket or futon.
Hot air will accumulate in the space of the groove 2 formed on the surface of 0. In other words, a warm air layer is formed in the many grooves 2 in the lower part of the body, increasing the warming effect. In addition, if you sweat while sleeping, moisture will be dispersed into the space of the grooves 2, and because the grooves 2 exist between the body and the surface material 1, there are few areas in close contact with each other, and the sticky feeling caused by sweat will be eliminated. It turns out.

In the case of dimensions a<b in Figure 3, full 2 is placed in the horizontal direction (dimension a) perpendicular to the body height, so the repulsive force from the groove 2 is removed, and the ventilation area between the body and the groove 2 is large. Since it can be removed, the moisture dissipation effect due to sweating is increased and it is effective. (
When the grooves 2 are formed in the height direction, the grooves 2 follow the body, the surface material 1 comes into close contact with the body, and the ventilation area of the grooves 2 decreases, reducing the moisture dissipation effect. ) Of course, the groove 2 may not be straight horizontally, but may also be diagonally.

The elastic body 3 is, for example, a soft urethane foam, and if it has the performance shown in Table 1 below, it will be sufficiently effective, and if necessary, if the perspiration dissipation effect is to be enhanced, the hardness may be increased, The method of increasing the depth of the heat sink can be selected as appropriate, and the heating effect can be improved by changing the number of cells and density to increase air permeability.

As for the surface material 1, if it is a plain woven cloth, it is sufficient to select the cloth grain etc. appropriately and take breathability into consideration.In particular, regarding hygiene,
Bedding is generally prone to inhabiting large numbers of dust mites, and there have been many reports of cotton futons containing 100,000 to 200,000 to 200,000 dust mites after several years of use, so consideration must be given to this point. . In order to prevent electrically heated bedding from becoming a home for dust mites, the dimension 4 of the ventilation means 8 of the adhesive 30 should be made small enough to prevent dust mites from passing through, as shown in Figure 4. The body width of the mites that are often attached to the bed is about 0.07m+a to 0.3mm, so if the two dimensions of the ventilation means 8, such as the cloth grain, are set to 0.05+++m or less, the mites can be removed while providing ventilation. Main body 1
To provide bedding that does not allow dust mites to enter the body and does not become a home for dust mites.

Further, the base material 31 of the adhesive material 30 does not need to be a woven fabric, and may be, for example, a nylon sheet with ventilation means 9 having a large number of holes, as shown in FIG. The same effect can be obtained by making C dimension almost equal to C dimension.

Furthermore, since the surface material 1 has a removable mechanism 6 such as a chuck, the heating element 4 and the elastic body 5 can be taken out. It is effective to use a washable electric bed blanket or the like that can be washed easily and the heating element 4 can be washed easily.

Effects of the Invention As described above, according to the present invention, the space indirectly formed by the groove has a heating effect and an effect of dissipating moisture during sweating, and provides a very good sleeping environment for achieving a good sleep state. can be provided.

In addition, because the surface material and elastic body are breathable, when the body naturally turns over while sleeping, when weight is applied to the part that was not bearing weight, the bomb effect generated by compression of that part of the elastic body generates electricity. The release of heated air within the heating bedding body has the advantage of warming the human body and promoting the dispersion of moisture during sweating, and is highly effective in practical use.
